STEAM-SEPARAT OR.

Application led January 21, 1915.

To all whom t may concern:

Be it known that I, WILLIAM S. ELLIOTT, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement inSteam-Separators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure l is a vertical section ofone form of steam separator embodying my invention;

Figs. 2 and 3 are sections taken, respectively, on the lines TI-II andIII-HT of Fig. l;

Fig. 4 is a view similar to Fig. l, but showing a modification; and

Fig. 5 is a section on the line V-V of Fig. 4. f

My invention has relation to steam separators of the receiver type, andis designed to provide a receiver of simple and durable construction andwhich is well adapted to stand the severe vibrations to which its partsare subjected when mounted upon an engine or the like.

The nature of my invention will be best understood by reference to theaccompanying drawings, in which I have shown two different embodimentsthereof, which will now be described, it being premised, however, thatvarious changes can be made in the construction and arrangement of theparts, without departing from the spirit and scope of my invention asdefined in the ap pended claims.

Referring first to the horizontal type of separator shown in Figs. 1 to3, the numeral 2 designates the receiver, which is shown as consistingof a large metal drum having heads 3, secured thereto in any suitablemanner. In the drawings, the heads are shown as welded within the endportions of the shell and this construction is preferable. The shell ofthe receiver is formed near its upper' end with diametrically oppositeopenings, through which is extended the steam pipe l. This pipe extendscontinuously across the drum, one end portion projecting at one side ofthe drum to form an inlet connection at 5, and the other end portionextending beyond the opposite side of the drum to form an outletconnection at 6. The connections areV preferably formed with couplingflanges 6. At this inlet end Specification of Letters Patent.

` portion, it is cut away to form an opening 7,

through which the steam enters the receiver. At its outlet end, it isout away within the receiver to form an opening 8, through which thesteam renters the pipe from the receiver. 8, a baflle plate 9 is securedin the pipe to prevent direct flow of steam therethrough. 10 designatesoblique battles or guards which prevent any creeping of the moisturecarried by the steam around the pipe il from the opening 7 to theopening 8, and also serve to deflect the steam. ll is a gage forindicating the amount of water in the receiver and l2 is a tap-offopening.

Between the two openings 7 andH The steam entering the inlet end ofthem' where it reenter-s the pipe through the opening 8. This gives avery effective separating action.

Figs. il and 5 show my invention applied to a vertical type ofseparator, the construction being in all substantial respects the" sameas that just described, except that the steam pipe passes verticallythrough the receiver instead of transversely. Tn these ligures, partscorresponding to similar parts in Figs. l, 2 and 3 are givencorresponding reference numerals with the letter a added thereto.

Receivers of this type when installed in steam lines, are subject tovibration and expansion and contraction of the line in which they areconnected. They are also frequently called upon to sustain the weight ofheavy pipes connected thereto, and in other cases the receiving chamberis supported on the pipe line direct. The bending moments have atendency to distort the form ofthe separator, as well as loosen thenozzles attached thereto from the receiving chamber.

In my improved construction, the steam pipe is carried continuouslythrough the receiver, and itself carries and supports the receiver. Asthe pipe is continuous, there is no strain whatever due to vibration,bending moment, etc., where this pipe makes its connection with thereceiving chamber, and the tendency to open up the joints is therebypractically eliminatedi I prefer to make the area of the inlet opening7, or 7a, materially larger than the outlet opening S, or 8a. This isclearly shown in Fig. 1. By so doing I cause the steam entering thechamber 2, or 2a, to have a much greater relative velocity than inleaving said chamber. This greatly increases the etectiveness of theseparator. It will also be noted that the baffles 10, or 10a, inaddition to preventing moisture from creeping around the pipe, alsoserve to divide the steam into two separate lines of flow. Thus thesteam is delivered from the opening 7, or 7, between these two battles,and divides, part of it turning and flowing back outside of one balileto the outlet opening, and another part outside of the other baiiie.This also increases the eliiciency of the separator.

I claim:

l. A steam separator of the receiver type, comprising a receiver, acontinuous steam pipe extending through the opposite walls of thereceiver and connected thereto, connecting means on the ends of thesteam pipe, the arrangement being such that the receiver is supported bythe pipe, said pipe being provided with inlet and outlet openingscommunicating with the receiver, the said openings being at oppositesides of the pipe, and the said pipe having` a partition wall thereinbetween the inlet and outlet openings, said pipe and receiver membersbeing formed separately and the receiver member being secured to saidpipe member, substantially as described.

2. A steam separator of the receiver type, comprising a receiver, acontinuous steam pipe extending through the opposite walls of thereceiver and connected thereto, connecting means on the ends of saidpipe, the arrangement being such that the structure is ward the inletopening, substantially as described.

3. A steam separator of the receiver type, comprising a receiver builtup of a cylindrr cal shell and sheet metal heads secured to the ends ofsaid shell, a continuous steam pipe extending through the opposite wallsof the receiver, said walls of the receiver being welded to the body ofthe pipe, connecting means on the ends of the pipe for securing it inposition in a steam line, said pipe being provided with inlet and outletopenings communicating with the receiver, the said openings in oppositesides of the pipe, a partition wall within the pipe between inlet andoutlet openings, and battles secured to the pipe wit in the receiver,said bailies extending away from the outlet opening toward the inletopening, substantially as described..

In testimony whereof, I have hereunto set my hand.
